The heater of this invention has an air intake positioned substantially at the .front of the car so that fresh air, .freeifrom road dust, will be admitted to,,and heated within, said heater, whereby fresh'warm air-is supplied to ftlle' car. The ,heater provides weather,-but inthe snmmer season {0f the year the air circulates rapidly through the means for economically warming 'jair and supplylhg the same to the 'cafduring' cold heater and into intimate contact with the 1 a be a parent-from the accompanying de- 'scriptitun'drawings and appended claims.

In Figs. 1 and 2 of the drawin s, A designates the cylinders of an automo ile engine,- and B the exhaust pipe or manifold, the latter having two branches b b which'ommunica te with the exhaust ports of engine A. The exhaust pipe Bginclines for a part of its length downwardlviand reacwardly frbm'er'rgine A, said pipe B entering a unitfier C of any usual form'f The mufller', to-

gtheii with-the inclined and rear part-1s of the pxhailstflpipe, extendjbelow the fl ooi-"D of 't'iri autgmoliile car or body E, the latter .;.b ing merge dottedlines in ig. 1, said the line floor D having an inclined section d and a dash d. All the parts referred to may be of the usual or any preferred construction, and they are described for the purpose, i'nainly, of illustrating an ordinary. car to which the heater of the presentjnvent-ion is adapted to be applied. In the example shown, engine A is of the four cylinder type having two exhaust ports which communicate with ,the branches 5 b of the exhaust pipe or manifold B, but as will be seen by reference to Fig. 7, the heater of this invention is adapted to be used in connection witha six cylinder engine having three exhaustports, as will hereinafter appear.

The heater, proper, for a four cylinder engine consists of sections F F and a hood H, although the number of sections may be increased when the heater is used in connection with a six cylinder engine. The sect-ions F F are positioned in' lapping engagement so that one section may telescope into the other, whereby the heater ismade. extensible for the purpose of adapting it to the exhaust. manifolds of different engines, the distance between the branch exhaust pipes ofwhich may, and commonly do, vary with relation to each other. I The sections F, F of the heater are provided with apertunes 7', f to receive the branches 1) b of the exhaust manifold.

As hereinbefore indicated, the heater is extensiblein the direction of its length, and is expansible circumferentially, whereby said heater is applicable to exhaust manifolds of different types of engines, which manifolds have their exhaust port oonnec tions spaced at difi'erent distances apart, said manifolds being of difl'erent diameters. The extension of the heater is secured by employing two or.more sections assembled in overlapping relation, each section 'being provided with an aperture, such as f or f, whereby the sections may be drawn out or extended while retaining them in lapping relation so that the distance between the apertures f, f in the respective sections will correspond to the distance between the exhaust ports of a particular engine. The expansion or contraction circumferentially of the heater is obtained by the construction illustrated more particularly in Figs. 5 and 6. As shown in Fig. 6, section F of the heater is divided or split lengthwise, said section being provided atone edge with a flange 10. the latter being doubled upon itself so to form a groove into which extends. a flange 11 of a. wing plate 12,. see Fig. 6. The section F"is provided at.- its other edge with a flange 13, the latter being doubled. upon itself in order to stiflen it, said flanges 10, 13 at the respective edges of the divided'section F being parallel to each other and extending lengthwise of the section. The wing plate 12 is thus attached to the flange 10 at one edge of thesection,

and this wing plate is positioned to have overlapping engagement with the other edge of said-section, which edgeis provided with the flange 13, whereby the wing plate is attached. to flangelO and is adapted to close the space in the section between the flanges 10, 13, when the section is expanded or contracted within a certain limit. Parallel flanges 10,13 or" section F are'provided with apertures through which pass the bolts .14 having nuts 15, the bolts operating to retain the flanges 10, 13 and the wing plate 12 in the positions to which they are adjusted when the section is enlarged or diminished in diameter. The other section F of the tubular heater is similar in construction to the section F, that is to say, the

section F is divided or split lengthwise. ()no edge of the section F is provided with a channeled flange 16, and the other edge is provided with a double flange 17. In the channeled flange lfi'of section F fits a depending flange 18 of a wing plate 19, the latter extending across the space between the parallel flanges 16, 17 at the respective edges'of section F so as to close the opening or space between the two flanges. At the meeting or lapping parts of sections F,

F, section F extends or fits into section Accordingly, the flanges 10, 13 of sec- F. tion F overlap the flanges 16, 17 of section F, and the wing plate 19 of section F over laps the corresponding wing plate 12 of section whereby the flanges and the Wing plates of the sections are-compactly disposed wvith respect to each other at the overlapping portionsof said section. It should noted that the flanges 16, 17 of section F are connected by bolts 20 which pass through suitable openings in the flanges in a similar manner to the bolts 14, but at the meeting or overlapping portions of the sections and their flanges, a slot or slots 21' are provided in one or more flanges so as to receive bolt or bolts 22, said. slot and bolt, as shown in dotted lines in Figs. 2 and 3, providing for the required longitudinal adjustment of sections F, F in order to extend or decrease the length of the tubular heater, whereby theopenings f, f are made to approach toward or recede from each other, for the purpose of adapting the tubular heater to receive branches I), Z) of the exhaust manifold, which branches may be located difl'erent dis tances apart in the diflerentst vlesor makes of the internal combustion en ines.

It is to be observed that the overlap between the flanges 10, 13 on section F, and 16, 17 on sectionF retains the. two sections F, F in alined relation longitudinally .of the heater tube, said flanges thus serving the purpose of means to preclude rotative movement of one section with respect to the other means whereby the sectionsv may be increased" or decreased in (litlltltttl for the reason that, the bolts or the screws can he turned in one contra r] 'v the screws so as to decreaee the diameter of the sections. whereby said HUlltlllfs are adapted for use in conjunction with exhaust inanifolds. the diameters of which (HP) in the ditlerent makes of engine Filltllfitll'ttll't. the sections F, F are divided lengthwisc. but the spaces or longitudinal openings in the sections are closed by the employment of the wing plates, as a result of which the sections may be increased or i'lecreased in dianieter as desired and there will he no tree spaces or openings through which air can flow, wherehy the sections are extensible loir gitudinally. expansible circumferentiall). and present continuous surfa es against the inflow of air s cep r-i the air tlows length wise through the hiatcr tube.

3 reference to Fig. 3 it will he noted that the longitudinal division in sections F. I extends through openings f. f in the heater tithe. Accordingly. the expansion or contraction of the heater tuhe, enlarges or diminishes the diameter of said openings, but it is important that the flow of air through openings f, j" be precluded around the branches of the exhaust manifold. To ac complish this end l employ packings (l. positioned partly within the openings and retained in fixed pt'isitions by tastening them to sections F. F. said pacliings lining composed of asbestos. or a compound of asbestos. or of any other appropriate material which is noncombustible. As shown. each packing consists of four semi-circular pieces of material. two of said pieces being as embled F0 as to form a complete. ring. and one ring being positioned on the inside of the heater tube. whereas the other rin positioned exteriorly to tl e heater tulie The sections composing the two packing rings in each opening are retained in position by semicircular clamping plates y. 1 positionei'l cxteriorlv and interiorly of the heater tube. and the e plates are fastened securel in position by screws. holts or riuts which are shown in Fig. 4 as passing: through the two packing rings and the series of lamping plates. The heater tnbc. is slotted. or the plate may he slotted as shown in Fig. 55. in order that the packing rings and their lamping plates mav be adjusted to bring the packing rings into close contact with branches 1). 7) of the exhaust manifold. The described construction enables the heater tube to be fitted to the sa d branches of the exhaust manifold in order to prevent the How of air around slli'l branches and into the heater tuhc.,hut a the parking are conipos d of tire resisting material. it is evid nt that the parts of the tubular heater in win tact with the highly heated bra'hches of the exhaust mauitold itlll not be att'ectcd by. or

deteriorated under the influence of. the exdircction so as to expand the sections and.

the nuts can he tightened on ha-ist gases from the engine. Furthermore. the expansion or contraction of the sections I. F composing the tubular heater to adapt them for ditt'erent sizes of exhaust. manifolds will bring" about a corresponding adjustment in the cctious of the packings and their clamping plates. and little. the tubular heater is constructed for use in connection with the exhaust manifolds and the branches thereof in the ditl'ereut makes of engines. I

The tulndar heater is positioned in close relation to engine A. and upon that side thereof having the exhaust manifold said tubular heater extending lengthwise of said manifold at that part of the latter into .which the exhaust is discharged directly from the engine. "lie hood or t'unnel- H is pro ided at the intake end of the tubular heater so that the funnel will extend Well forward of the engine cylinders and be elevated substantially above said cylinders, thus locating the funnel directly at. the rear of the radiator, whereby t'resh air substa'n' tiall free from road dust will be supplied to the tubular heater. The tunnel has its cpcn end close to a fan positioned at the rear of the radiator shown in Fig. 1 in that style of engine which is cooled by the operation of a rotary tan. and. accordingly. when such a fan is used. a certain amount of air will be blown through the funnel and the tubular heater, as a result of which a forced cirou lation, of air takes place in contact with the highly heated exhaust manifold so as to reduce the tennieratiue of said exhaust manifold durinai the summer season of the year. The tunnel l is tapering. but the angle of the taper on one side is greater than on the otter. as shown in Fig. 2. as a result. of which the funnel is provided with an intake of large diameter and is positioned in such relation to the engine that a certain amount of air will be blown into the engine by the operation of the fan. The tunnel is provided with a cylindrical section it and with a head it. the latter a ting to limit the inward movement of said tunnel with respect to secticn F. Furtlm-morc.the funnel and its tuhular section 11 are divided longitudinally and provided with side flanges 12 to receive the bolts 71 whereby the funnel is rendered expansihle and centractible in'order to make it conform to the expansion or contraction of the heater tube. The space between the flanges and the divided tunnel is closed by a win; plate I! indicated in Fig. 3. said wing plate being similar to the wing plates 12. 19 of sections F. I respectively. The tubular inner end ii of the tunnel is received \vit'hih the t'crward end portion of section F so as to hare overlapping relation theretin and the warm air, in a fresh condition and free from dust, is adapted to be supplied into one or both compartments of the car.

I have heretofore described the invention in connection with a four cylinder engine having two branche b, 1/ leading to the exhaust manifold, but in Fig. 7 of the dravvings I have shown a construction of the tubula'r heater which is adapted for use in connection with a six cylinder engine having three branches to th; exhaust manifold. As disclosed in said figure, the tubular heater consists of the sections F, F having openings f. 1'', respectively, and an additional section F positioned between the sections F, F, said intermediate section F being provided with an opening f, for the purpose of receiving the branch of the exhaust mam-- fold. The section F is constructed similarly to the sections F, F. that is by providing it with flanges ands wing plate, so as to permit expansion and contraction of said section F furthermore, section F is rovided with ackings similar to the packmgs (l, G, and t 1e end portions of section F are in lapping engagement with the sections F,

F, respectively, so as to provide for the in- "crease or decrease in the total length of the tubular heater.
